Diogenes Laertius’ Lives of Eminent Philosophers occupies a unique place in the history of Western philosophy. In addition to its valuable summaries of the doctrines of philosophers and their schools, it is often the best, or, indeed, the only source available for biographical details of many figures. Yet, as a work, it is often criticized for a lack of originality and critical judgement, notable only because it happened to survive while all other philosophical histories of the era did (...) not, or useful only because Diogenes had access to sources which are now lost to us. White sets himself against this pessimistic interpretation of Diogenes, and endeavors to show both the genuine merits of his work and his worth as a historian. (shrink)

A sentence in Book 7 of Diogenes Laertius’s Lives states that, according to the Stoics, the four elements are “unqualified substance, i.e. matter.” Scholars have noted that this appears to conflict with the Stoics’ distinction between principles and elements. Different solutions have been proposed, from dismissing the sentence entirely to emending the text. This note proposes a new interpretation according to which the standard reading of the text can be retained.

This is the translation of Protagoras' life from Diogenes Laertius' "Lives of eminent Philosophers" (IX, 8).

The option of being ‘spiritual but not religious’ deserves much more philosophical attention. That is the aim here, taking the work of Robert Solomon as a starting point, with focus on the particular issues around viewing life as gift. This requires analysis of ‘existential gratitude’ to show that there can be gratitude for things without gratitude to someone for providing things, and also closer attention to the role that metaphor plays in cognition. I consider two main concerns with gift (...) and gratitude thinking, that the nonreligious justification is too instrumentalist in its approach and that viewing life as gift, whether in a religious or nonreligious way, is simply too optimistic.

David Hume, a leading Scottish Enlightenment philosopher using empirical investigation, examines and explains his view on human nature, society, and morality in A Treatise of Human Nature (Treatise) and in An Enquiry Concerning the Principles of Morals (Enquiry). In Dr. Jekyll and Mr. Hyde (Jekyll and Hyde), Robert Louis Stevenson draws from the Enlightenment’s empirical explorations in the study of the individual and society, to tell a story examining human nature.

How demanding is the virtuous life? Can virtue exist alongside hints of vice? Is it possible to be virtuous within a vicious society? A line of thinking running through Diogenes and the Stoics is that even a hint of corruption is inimical to virtue, that participating in a vicious society makes it impossible for a person to be virtuous. One response to this difficulty is to claim that virtue is a threshold concept, that context sets a threshold for what (...) is considered virtuous. On this way of thinking, what counts as virtuous in one society may be more demanding than what passes for virtuous in another. This response seems plausible when considering that virtue-theoretic terms like `honest' are gradable adjectives. Many gradable adjectives, like `tall' and `expensive,' have contextual thresholds that shift depending on the situation, and so is tenable that virtue-theoretic adjectives might function with contextual thresholds as well. A major difficulty for this response, however, is that virtue terms are absolute gradable adjectives, a variety of gradable adjectives that do not require a contextual threshold. Absolute gradable adjectives instead draw their truth conditions from their maximal degree, suggesting that Diogenes and the Stoics were correct to think that virtue is incompatible with even a small degree of vice.

Charles S. Peirce (†1914) is often referred to as the founder of contemporary semiotics. Peirce provided the community of inquiry with a very convincing explanation of what a sign is. Peirce's definition of the sign bears a striking resemblance to that proposed in the 1606 volume of the CJC, the Coimbra Jesuit Course, authored by Sebastião do Couto (†1639). The community of inquiry holds the belief that Peirce drew from the writings of Couto to arrive at his triadic conception (...) of the sign. Could it be that the effect of the CJC on Peirce is restricted to the definition of the sign? What can anyone say so far on the Peirce-CJC relation? Our ultimate purpose here is to provide a contribution to settling such doubts. (shrink)

This paper argues that despite recent tendencies to minimize the differences between Posidonius and the Early Stoics, there are some important aspects of Stoic ethics in which Posidonius deviated from the orthodox doctrine. According to two passages in Diogenes Laertius, Posidonius counted health and wealth among the goods and held that virtue alone is insufficient for happiness. While Kidd in his commentary dismissed this report as spurious, there are good reasons to take Diogenes’ remarks seriously. Through a (...) careful analysis of the sources, in particular of Galen's De placitis Hippocratis et Platonis, this article offers a new interpretation of Posidonius’ ethics. It sheds light on Posidonius’ theory of virtues and shows that Posidonius must have granted a special status to things like health and wealth even if he did not regard them as genuine goods.

Epicurus strongly discouraged sex, marriage, and the rearing of children. This paper looks at some of the primary evidence for these claims, clears up a translation of one passage, and emends another passage. (The emendation has been accepted into Dorandi's new edition of Diogenes Laertius).

This paper discusses the reports in Diogenes Laertius and in Sextus Empiricus concerning the classification of propositions. It is argued that the material in Sextus uses a source going back to the Dialectical school whose most prominent members were Diodorus Cronus and Philo of Megara. The material preserved in Diogenes Laertius, on the other hand, goes back to Chrysippus.

Diogenes Laertius (8.63-6) preserves a fascinating account of the Presocratic philosopher Empedocles' life. There, drawing on evidence from Aristotle, Xanthus, and Timaeus of Tauromenium, the biographer provides several anecdotes which are meant to demonstrate how Empedocles had, contrary to expectation, been a democratic philosopher - a paradox of itself in Ancient Greece. This article unpacks the complex web woven by Diogenes and argues that there is no good reason to assume that Empedocles was indeed a democratic philosopher, (...) and moreover, that neither Xanthus nor Aristotle thought him so. Indeed, what Diogenes actually preserves for us is the Hellenistic biographer Timaeus' critical dialectical engagement with the versions Aristotle and Xanthus, in his anachronistic bid to render Empedocles a democratic hero.

Diogenes Laertius reports (in his Lives of Eminent Philosophers ix 19) that Xenophanes of Colophon stated that ta polla hêssô nou (in some sense, ‘that the many give way to mind’). After reviewing four alternative but unsatisfactory ways of understanding the remark I argue that it is best understood as ‘the multitude of things (i.e. the cosmos) gives way to—is mastered by—the (divine) mind.’ When understood in this way the remark establishes Xenophanes as one of the earliest Greek (...) thinkers to hold that events throughout the cosmos take place under the control of a supremely powerful divine intelligence.

Kant’s account of “the radical evil in human nature” in the 1793 Religion within the Bounds of Reason Alone is typically interpreted as a reworking of the Augustinian doctrine of original sin. But Kant doesn’t talk about Augustine explicitly there, and if he is rehabilitating the doctrine of original sin, the result is not obviously Augustinian. Instead Kant talks about Stoic ethics in a pair of passages on either end of his account of radical evil, and leaves other clues that (...) his argument is a reworking of an old Stoic problem. “Radical evil” refers to the idea that our moral condition is — by default and yet by our own deed — bad or corrupt; and that this corruption is the root (radix) of human badness in all its variety, ubiquity, and sheer ordinariness. Kant takes as his premise a version of the Stoic idea that nature gives us “uncorrupted starting points” (Diogenes Laertius 7.89). What sense can be made of the origin of human badness, given such a premise? Kant’s account of radical evil is an answer to this old Stoic problem, which requires a conception of freedom that is not available in his Stoic sources. (shrink)

At the heart of the Stoic theory of modality is a strict commitment to bivalence, even for future contingents. A commitment to both future truth and contingency has often been thought paradoxical. This paper argues that the Stoic retreat from necessity is successful. it maintains that the Stoics recognized three distinct senses of necessity and possibility: logical, metaphysical and providential. Logical necessity consists of truths that are knowable a priori. Metaphysical necessity consists of truths that are knowable a posteriori, a (...) world order according to certain metaphysical principles and natures that god crafts within the constraints of matter. Finally, what is providentially necessary is what occurs according to the chain of fate, but only once it is in process or past. -/- The method of the paper is a close reading of Diogenes Laertius 7.75, adducing broad textual evidence along the way, to show that the Stoic theory of modality embraces Philonian possibility, both that which is capable of being true as a matter of logical consistency, and that which is possible according to the bare fitness of the entity. What differentiates the Stoics from Philo is their additional commitment to possibility as opportunity, resisting the collapse of determinism into necessity. (shrink)

Immediately upon the death of Plato in 347 BCE, philosophers in the Academy began to circulate stories involving his encounters with wisdom practitioners from Persia. This article examines the history of Greek perceptions of Persian wisdom and argues that the presence of foreign wisdom practitioners in the history of Greek philosophy has been undervalued since Diogenes Laertius.

In this paper I defend the existence of a Dialectical school proper against criticisms brought forward by Klaus Döring and by Jonathan Barnes. Whereas Döring claims that there was no Dialectical school separate from the Megarians, Barnes takes issue with my claim (argued for in “Dialektiker und frühe Stoiker bei Sextus Empiricus”) that most of the reports in Sextus on the dialecticians refer to members of the Dialectical school. Barnes contends that these dialecticians are in fact Stoic logicians. As against (...) Döring, I argue that the passage in Diogenes Laertius II 113 (first drawn attention to by David Sedley) which talks of a the Megarian Stilpo winning over disciples from the Dialecticians is not refuted by Döring’s arguments. It clearly shows that the Dialecticians and the Megarians at the time were taken to be different philosophical sects. As against Barnes I insist on the differences between the report in Ps.-Galen’s Historia 9 and the Sextan report on the theory of sign in AM VIII. These reports offer incompatible definitions of the indicative sign. Moreover, the classification of simple propositions reported by Sextus at AM VIII 96f. cannot be a truncated version of the (Stoic) list to be found in Diogenes Laertius VII 69f. since in Sextus’ report one of the three classes of simple propositions is labelled middle (meson). This is a certain sign that we are dealing with a triad, and hence that this list is meant to be complete. Therefore the classification found in Sextus and attributed to the dialecticians and the one in Diogenes Laertius reporting Stoic material do come from different sources. (shrink)

There are some tantalizing suggestions that Pyrrhonian skepticism has its roots in ancient India. Of them, the most important is Diogenes Laertius’s report that Pyrrho accompanied Alexander to India, where he was deeply impressed by the character of the “naked sophists” he encountered (DL IX 61). Influenced by these gymnosophists, Pyrrho is said to have adopted the practices of suspending judgment on matters of belief and cultivating an indifferent composure amid the vicissitudes of ordinary life. Such conduct, and (...) the attitudes that it embodied, became inspirations to later skeptical thinkers. It is a fact that practices of the sort attributed to Pyrrho are richly evident in a number of ancient Indian philosophical and ascetic movements. On this basis, attempts have been made to determine the identity of these gymnosophists and, further, to pinpoint the dialectical tropes within Pyrrhonism that may have their basis in Indian thought. But despite these attempts, and in the absence of any new discoveries, these suggestions will likely remain just that. The paucity of the historical data and the problematic nature of the data itself prevent us from reconstructing a solid bridge between ancient India and Greek skepticism that may serve as the basis of robust historical theorizing. Classical India does, however, lay claim to a sophisticated and diverse culture of epistemological reflection, which includes a number of innovative skeptical thinkers deserving study on their own merits. This chapter is meant to provide such a study, or perhaps more accurately, a prolegomena for such. After some initial ground-laying, I will discuss three leading Indian skeptics and situate them historically and conceptually within the network of competing schools that comprise classical Indian philosophy. They are Nāgārjuna (c. 150 CE), the founder of Madhyamaka Buddhism, Jayarāśi (c. 800), associated with the Indian materialist tradition, and Śrīharṣa (c. 1150), a thinker connected to the school of Nondual (Advaita) Vedānta.

Epicurean philosophy, as Epicurus's teachings became known, was used as the basis for how the community lived and worked. At the time, founding a school and teaching a community of students was the main way philosophical ideas were developed and transmitted. Greek philosopher Aristotle (384–322 BCE), for instance, founded a school in Athens called the Lyceum. Epicurus and his disciples believed either there were no gods or, if there were, the gods were so remote from humans that they were not (...) worth worrying about. Similarly, humans would not have to worry about the afterlife. Instead, humans should live by maximizing their pleasure. The highest pleasure was to be found in the absence of pain. Epicurus taught that humans could maximize their pleasure by living simply and enjoying those impulses that are natural to humans. These impulses include the need to eat and the desire for good friends and company. The Principal Doctrines are 40 statements outlining the basis for the beliefs of Epicurus and his followers about how to lead a good life. Epicurus's other philosophical beliefs (such as his belief that existence was composed of indivisible particles called atoms) are expressed in other writings. Almost none of Epicurus's original writings survive to the present day. His works, including the Principal Doctrines, are known to us because of the work of later writers. In the 3rd century CE, Diogenes Laërtius reproduced Epicurus's writings in Lives, Teachings, and Sayings of Famous Philosophers. Produced centuries after Epicurus's death, such collections may not be Epicurus's precise words or formulations. The Principal Doctrines should thus be regarded as the core principles not only of Epicurus but also of his followers, the Epicureans. (shrink)

Robert Nozick initiated one of the most inspired and inspiring discussions in political philosophy with his 1974 response in Anarchy, State, and Utopia to John Rawls’s 1971 account of distributive justice in A Theory of Justice. These two works have informed an enormous amount of subsequent, especially liberal, discussions of economic justice, where Nozick’s work typically functions as a resource for those defending more right-wing (libertarian) positions, whereas Rawls’s has been used to defend various left-wing stances. Common to these (...) discussions, as found in politics generally (where similar kinds of arguments frequently are used to defend right and the left-wing policies and conclusions) is that they end in rather stubborn stalemates: the right defending minimal states while the left defends more extensive states. Interesting, too, is that both Nozick and Rawls take themselves to be consistent with, inspired by, and furthering Kant’s freedom project in the development of their own theories of justice. In this paper, I start by outlining the structures of these debates with an emphasis on the original disagreements between Nozick and Rawls. I then show how neither theory actually employed Kant’s own theory of justice, but rather drew on or out (presumed) implications of his ethical theory. In the final sections, I argue that if Nozick and Rawls had instead used Kant’s theory of justice and not his ethics, not only would their individual theories have been stronger, but they could have found ways of overcoming the unproductive stalemates that characterize their own as well as subsequent related discussions of economic justice as we currently find them in much scholarly and contemporary political debate.

This chapter presents a historical study of how science has developed and of how philosophical theories of many sorts – philosophy of science, theory of the understanding, and philosophical theology – both enable and constrain certain lines of development in scientific practice. Its topic is change in the legitimacy or acceptability of scientific explanation that invokes purposes, or ends; specifically in the argument from design, in the natural science field of physico-theology, around the start of the eighteenth century. ... The (...) context that produced physico-theology was clearly religious and political. It is unsurprising that a large body of Protestant intellectuals well-placed in a relatively peaceful society with a strong tradition of open speech, would develop links between science and critical discussion of both divinity and the Bible. There were also bounds to the discussion, as Newton, who chose to sit on the sidelines, knew well. Many others on Europe’s continent lived much more intimately with religious division as well as the reminder, in 1633, of Galileo’s failure to arrange a peaceable arrangement between science and religion. These aspects of the rise of physico-theology have not been the focus of this chapter, which has surveyed the philosophical and social origins found in the English context. Science, philosophy of science and other English philosophical currents – most particularly the theory of ideas and understanding that we are familiar with in its later development by John Locke – were formative for a field that might alternatively have been called ‘empirical natural theology.’ Prior shifts in religious sensibility that emptied the Book of Nature of much of its content also prepared the ground. Other philosophical and theological currents not discussed here – most notably theories of divine agency and predestination – and other philosophical trends – the rise of Spinoza’s challenge to such natural theology on the continent – also had both shaping and limiting influences upon the field. Finally, philosophers, including natural philosophers, did much more to promote physico-theology than just write about it: Boyle in particular provided a very important launch pad for the further development of an already healthy tradition of natural theology with his named lectureship, which drew the interest of others in the Royal Society, most notably Isaac Newton, and which spawned two of the most influential physico-theological tracts shortly before and shortly after the turn of the eighteenth century.

Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are “black boxes.” The initial response in the literature was a demand for “explainable AI.” However, recently, several authors have suggested that making AI more explainable or “interpretable” is likely to be at the cost of the accuracy of these systems and that prioritizing interpretability in medical AI may constitute a “lethal prejudice.” In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realized. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems, may itself constitute a form of lethal prejudice that may diminish the benefits of AI to—and perhaps even harm—patients.

Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting similar results. However, the results indicate that architects, though visual experts, may not employ the holistic processing strategy observed in their previously studied counterparts. Participants (n = 48, 24 architects, 24 (...) naïve) were asked to find targets in chest radiographs and perspective images. All images were presented in both gaze-contingent and normal viewing conditions. Consistent with a holistic processing model, we expected two results: (1) architects would display a greater difference in saccadic amplitude between the gaze- contingent and normal conditions, and (2) architects would spend less time per search than an undergraduate control group. We found that the architects were more accurate in the perspectival task, but they took more time and displayed a lower difference in saccadic amplitude than the controls. Our research indicates a disjunctive conclusion. Either architects are simply different kinds of visual experts than those previously studied, or we have generated a task that employs visual expertise without holistic processing. Our data suggest a healthy skepticism for across-the-board inferences collected from a single domain of expertise to the nature of visual expertise generally. More work is needed to determine whether holism is a feature of all visual expertise. (shrink)

Decisions are made under uncertainty when there are distinct outcomes of a given action, and one is uncertain to which the act will lead. Decisions are made under indeterminacy when there are distinct outcomes of a given action, and it is indeterminate to which the act will lead. This paper develops a theory of (synchronic and diachronic) decision-making under indeterminacy that portrays the rational response to such situations as inconstant. Rational agents have to capriciously and randomly choose how to resolve (...) the indeterminacy relevant to a given choice-situation, but such capricious choices once made constrain how they will choose in the future. The account is illustrated by the case of self-interested action in situations where it is indeterminate whether you yourself will survive to benefit or suffer the consequences. The conclusion emphasizes some distinctive anti-hedging predictions of the account. (shrink)

Fear is a preventer, sometimes robustly so. When fear robustly prevents, it changes or diminishes what an agent is able to do. Various popular conceptions of fear focus on its negative role: fear sometimes prevents us from acting as we should, as in certain cases of akrasia. But by the same token, fear sometimes prevents us from acting as we shouldn’t, as in certain other cases of inverse akrasia. We end with a plea on behalf of fear, both in light (...) of its preventing role and its broader connection to other ways we express concern, in particular, to hope. (shrink)

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

I defend the widely-held view that morally worthy action need not be motivated by a desire to promote rightness as such. Some have recently come to reject this view, arguing that desires for rightness as such are necessary for avoiding a certain kind of luck thought incompatible with morally worthy action. I show that those who defend desires for rightness as such on the basis of this argument misunderstand the relationship between moral worth and the kind of luck that their (...) argument employs. Consequently, the argument provides no reason to doubt the popular view that a desire for rightness as such is no part of virtue. I conclude by suggesting that a family of worries about merely accidentally right action presuppose one side of the recent debate about objectivism and perspectivism about moral rightness. (shrink)

Worlds where things divide forever ("gunk" worlds) are apparently conceivable. The conceivability of such scenarios has been used as an argument against "nihilist" or "near-nihilist" answers to the special composition question.

Inflicting harm is generally preferable to inflicting death. If you must choose between the two, you should generally choose to harm. But prenatal harm seems different. If a mother must choose between harming her fetus or aborting it, she may choose either, at least in many cases. So it seems that prenatal harm is particularly objectionable, sometimes on a par with death. This paper offers an explanation of why prenatal harm seems particularly objectionable by drawing an analogy to the all-or-nothing (...) problem. It then argues that this analogy offers independent support for the ‘voluntarist’ view that at least some parental role obligations are grounded in the choice to be a parent. (shrink)

While intimately familiar, gender eludes theorizing. We argue that well-known challenges to gender’s analysis originate in a subtle ambiguity: questions about gender sometimes express questions about gender categories themselves (e.g., womanhood, manhood, and so on), while at other times expressing questions about what makes someone a member of these categories. Distinguishing these questions accentuates gender’s connections to morality, making a novel “antirealist” view of gender, or as we call it, “unrealist” view, especially natural. Gender’s relations to identity, sex, and social (...) position are illuminated along the way. Taking cues from both historical and contemporary debates in metaethics about the roles that attitudes can play in metaphysical and semantic analysis, we introduce and begin developing a comprehensive non-ameliorative framework for explicating gender’s nature and our thought and talk about it. In a slogan, on the view we defend, you belong to the gender category to which you intrinsically desire to belong. (shrink)

Joyce (1998) gives an argument for probabilism: the doctrine that rational credences should conform to the axioms of probability. In doing so, he provides a distinctive take on how the normative force of probabilism relates to the injunction to believe what is true. But Joyce presupposes that the truth values of the propositions over which credences are defined are classical. I generalize the core of Joyce’s argument to remove this presupposition. On the same assumptions as Joyce uses, the credences of (...) a rational agent should always be weighted averages of truth value assignments. In the special case where the truth values are classical, the weighted averages of truth value assignments are exactly the probability functions. But in the more general case, probabilistic axioms formulated in terms of classical logic are violated—but we will show that generalized versions of the axioms formulated in terms of non-classical logics are satisfied.

Some moral theorists argue that being an innocent beneficiary of significant harms inflicted by others may be sufficient to ground special duties to address the hardships suffered by the victims, at least when it is impossible to extract compensation from those who perpetrated the harm. This idea has been applied to climate change in the form of the beneficiary-pays principle. Other philosophers, however, are quite sceptical about beneficiary pays. Our aim in this article is to examine their critiques. We conclude (...) that, while they have made important points, the principle remains worthy of further development and exploration. Our purpose in engaging with these critiques is constructive — we aim to formulate beneficiary pays in ways that would give it a plausible role in allocating the cost of addressing human-induced climate change, while acknowledging that some understandings of the principle would make it unsuitable for this purpose.

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy.

Are counterfactuals with true antecedents and consequents automatically true? That is, is Conjunction Conditionalization: if (X & Y), then (X > Y) valid? Stalnaker and Lewis think so, but many others disagree. We note here that the extant arguments for Conjunction Conditionalization are unpersuasive, before presenting a family of more compelling arguments. These arguments rely on some standard theorems of the logic of counterfactuals as well as a plausible and popular semantic claim about certain semifactuals. Denying Conjunction Conditionalization, then, requires (...) rejecting other aspects of the standard logic of counterfactuals, or else our intuitive picture of semifactuals. (shrink)

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

It is widely thought that functionalism and the qualia theory are better positioned to accommodate the ‘affective’ aspect of pain phenomenology than representationalism. In this paper, we attempt to overturn this opinion by raising problems for both functionalism and the qualia theory on this score. With regard to functionalism, we argue that it gets the order of explanation wrong: pain experience gives rise to the effects it does because it hurts, and not the other way around. With regard to the (...) qualia theory, we argue that it fails to capture the sense in which pain 's affective phenomenology rationalises various bodily-directed beliefs, desires, and behaviours. Representationalism, in contrast, escapes both of these problems: it gets the order of explanation right and it explains how pain 's affective phenomenology can rationalise bodily-directed beliefs, desires, and behaviours. For this reason, we argue that representationalism has a significant advantage in the debates about pain 's affective phenomenology. We end the paper by examining objections, including the question of what representationalists should say about so-called ‘disassociation cases’, such as pain asymbolia. (shrink)

I propose and defend a novel view called “de se consequentialism,” which is noteworthy for two reasons. First, it demonstrates—contra Doug Portmore, Mark Schroeder, Campbell Brown, and Michael Smith, among others—that agent-neutral consequentialism is consistent with agent-centered constraints. Second, it clarifies the nature of agent-centered constraints, thereby meriting attention from even dedicated nonconsequentialists. Scrutiny reveals that moral theories in general, whether consequentialist or not, incorporate constraints by assessing states in a first-personal guise. Consequently, de se consequentialism enacts constraints through the (...) very same feature that nonconsequentialist theories do. (shrink)

Majority cycling and related social choice paradoxes are often thought to threaten the meaningfulness of democracy. But deliberation can prevent majority cycles – not by inducing unanimity, which is unrealistic, but by bringing preferences closer to single-peakedness. We present the first empirical test of this hypothesis, using data from Deliberative Polls. Comparing preferences before and after deliberation, we find increases in proximity to single-peakedness. The increases are greater for lower versus higher salience issues and for individuals who seem to have (...) deliberated more versus less effectively. They are not merely a byproduct of increased substantive agreement. Our results both refine and support the idea that deliberation, by increasing proximity to single-peakedness, provides an escape from the problem of majority cycling. (shrink)

A far-reaching and influential view in evolutionary biology claims that species are cohesive units held together by gene flow. Biologists have recognized empirical problems facing this view; after sharpening the expression of the view, we present novel conceptual problems for it. At the heart of these problems is a distinction between two importantly different concepts of cohesion, what we call integrative and response cohesion. Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene flow that (...) are central to the view we discuss. We conclude by tracing four broader implications for the study and conceptualization of species. (shrink)

The 1994 US spectrum auction is now a paradigmatic case of the successful use of microeconomic theory for policy-making. We use a detailed analysis of it to review standard accounts in philosophy of science of how idealized models are connected to messy reality. We show that in order to understand what made the design of the spectrum auction successful, a new such account is required, and we present it here. Of especial interest is the light this sheds on the issue (...) of progress in economics. In particular, it enables us to get clear on exactly what has been progressing, and on exactly what theory has – and has not – contributed to that. This in turn has important implications for just what it is about economic theory that we should value. (shrink)

A vexing problem in contemporary epistemology—one with origins in Plato’s Meno—concerns the value of knowledge, and in particular, whether and how the value of knowledge exceeds the value of mere true opinion. The recent literature is deeply divided on the matter of how best to address the problem. One point, however, remains unquestioned: that if a solution is to be found, it will be at the personal level, the level at which states of subjects or agents, as such, appear. We (...) take exception to this orthodoxy, or at least to its unquestioned status. We argue that subpersonal states play a significant—arguably, primary—role in much epistemically relevant cognition and thus constitute a domain in which we might reasonably expect to locate the “missing source” of epistemic value, beyond the value attached to mere true belief.

This book presents a philosophical conception of logic -- "logical expressivism"-- according to which the role of logic is to make explicit reason relations, which are often neither monotonic nor transitive. It reveals new perspectives on inferential roles, sequent calculi, representation, truthmakers, and many extant logical theories.

We distinguish between two different strategies in methodology of economics. The big picture strategy, dominant in the twentieth century, ascribed to economics a unified method and evaluated this m...

This essay takes a critical look at aesthetics as the basis for nature preservation, presenting three reasons why we should not rely on aesthetic foundations to justify the environmentalist program. First, a comparison to other kinds of aesthetic value shows that the aesthetic value of nature can provide weak reasons foraction atbest. Second, not everything environmentalists want to protect has positive aesthetic qualities. Attempts have been made to get around this problem by developing a reformist attitude towards natural aesthetics. I (...) argue that these approaches fail. Third, development can be as aesthetically positive as nature. If it is simply beauty we are looking for, why can't the beauty of a wellconstructed dam or a magnificent skyscraper suffice? (shrink)

Suppose that you're certain that a certain sentence, e.g. "Frida is tall", lacks a determinate truth value. What cognitive attitude should you take towards it—reject it, suspend judgment, or what else? We show that, by adopting a seemingly plausible principle connecting credence in A and Determinately A, we can prove a very implausible answer to this question: i.e., all indeterminate claims should be assigned credence zero. The result is striking similar to so-called triviality results in the literature on modals and (...) conditionals. (shrink)

This chapter examines two ways in which liberal thinkers have appealed to claims about disagreement in order to defend a principle of free speech. One argument, from Mill, says that free speech is a necessary condition for healthy disagreement, and that healthy disagreement is conducive to human flourishing. The other argument says that in a community of people who disagree about questions of value, free speech is a necessary condition of legitimate democratic government. We argue that both of these arguments, (...) in their standard guises, are premised upon contestable views about the realpolitik of disagreement in a liberal society. (shrink)
